// FIXME: "...However, we also wanted to integrate the window.onerror feature in
// HTML5. So after we've fired an "error" event, if .preventDefault() was
// never called on the event, we fire an error event on the window (can't
// remember if this happens before or after we abort the transaction).
// This is a separate event, which for example means that even if you
// attach a capturing "error" handler on window, you won't see any events
// unless an error really went unhandled. And you also can't call
// .preventDefault on the error event fired on the window in order to
// prevent the transaction from being aborted. It's purely there for
// error reporting and distinctly different from the event propagating to
// the window.
//
// This is similar to how "error" events are handled in workers.
//
// (I think that so far webkit hasn't implemented the window.onerror
// feature yet, so you probably don't want to fire the separate error
// event on the window until that has been implemented)." -- Jonas Sicking
